* Vehicle Identification Number (VIN): The VIN contains coded information about the vehicle, including the engine. You can decode the VIN using a VIN decoder website (many are free online) or by contacting a Chevrolet dealership. This is the most reliable method.
* The Engine Bay: Look for a sticker or plate on the engine or the engine bay itself. This often lists engine specifications, including displacement (engine size). It might be near the oil fill cap or on a component like the valve cover.
* Owner's Manual: If you have the original owner's manual, it will specify the engine size.
* Vehicle Registration Documents: Your registration or title might list the engine size, though this isn't always the case.
Important Note: The 1989 Chevy Cavalier came with several different engine options. Therefore, just knowing the year and model isn't enough to determine the engine size. You need to use one of the methods above to find the specific engine size of *your* Cavalier.
